vismAal2CidState
Module: CISCO-VISM-ATM-TRUNK-MIB
OID (symbolic): CISCO-VISM-ATM-TRUNK-MIB::vismAal2CidState
OID (numeric): 1.3.6.1.4.1.351.110.5.5.3.4.1.1.16
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: Indicates the state of the CID. 'cidStateActive' : The CID is in service and operational. 'cidStateFailed' : The CID is in service but not operational, e.g. because the PVC that the CID belongs to is receiving F5(Operation, Administration and Maintenance Flow) level alarm.
When VISM sees alarm on a CID (network side) sets this object to 'cidStateFailed', and an AIS will be sent on the ds0(Time Division Multiplexed voice channel) that this CID corresponds to.
If the whole PVC is in alarm then all the CIDs on that PVC will be set to 'cidStateFailed', trapVismChanFailed trap will be sent and all the ds0's that corresponds to each of the CIDs on this PVC will be in alarm.
If VISM sees an alarm on a ds0 in a line then an RAI(Remote Alarm Indication) will be sent on the CID that corresponds to this ds0, however the CID will not be put in failed state.
What is vismAal2CidState?
This read-only INTEGER object reports whether a CID is cidStateActive (in service and operational) or cidStateFailed (in service but not operational, e.g., due to an F5 OAM alarm on the containing PVC). This is the direct operational health indicator for a specific voice channel, distinct from whether it's administratively configured at all. An admin investigating a specific failed call would check this object first to confirm the CID itself reports a failed state rather than a healthy but misconfigured one.
